Title: Device for measuring and controlling molten material surface position of semiconductor single crystal producing device
Inventor: HIRAISHI YOSHINOBU
IPC: C30B15/00
Filed: 1992-04-17
Abstract: PURPOSE:To precisely and stably maintain the surface of a molten material at a specified position when a single crystal is pulled up in the semiconductor single crystal producing device by the CZ method. CONSTITUTION:A laser beam emitted from a laser oscillator 10 is passed through a scanning mirror 13 and an f-theta lens 12 and made into the parallel beams to scan the plane perpendicular to the surface 1 of a molten material projected on the surface 1 at an incident angle of theta. Since a light receiving part 16 is provided with a horizontally long slit 16b on the front of a photosensor 16a, only the light reflected from the surface 1 at an angle theta of reflection is received by the light receiving part 16. The canning position of the projected light is detected by a control part 20 when the reflected light is detected by the light receiving part 16, and a command signal is outputted to a crucible driving mechanism 6 so that the position coincides with the press scanning position. Consequently, the molten material surface position is precisely measured and controlled regardless of the fluctuation of the melt surface.

Title: Spindle motor with hydraulic regulation mechanism
Inventor: ABE SADAHIRO
IPC: H02K5/16
Filed: 1995-05-24
Abstract: PURPOSE: To eliminate rotational fluctuation while preventing increase of power consumption by filling the rotor shaft and the bearing part in stator part with lubricant and making a micro lubrication hole in the bearing part at the stator part thereby keeping the hydraulic pressure at a constant level regardless of fluctuation in the hydraulic pressure or temperature at the time of inserting the rotor shaft. CONSTITUTION: One or more micro lubrication hole 4 for regulating the hydraulic pressure is made in the side face part at the stator part 3 in order to keep the hydraulic pressure in the stator part 3 at a constant level. When the hydraulic pressure in the stator part 3 increases at the time of inserting the shaft 2a at rotor part 2 or temperature rise, lubricant is pushed out to the outside in order to suppress inner hydraulic pressure rise thus preventing the shaft 2a at rotor part 2 from being pushed up. When the hydraulic pressure in the stator part 3 is decreased due to temperature drop, lubricant is drawn into the lubrication hole 4 in order to suppress hydraulic pressure drop in the stator part 3. This structure ensures stabilized rotation and current consumption without applying any excess load to the rotor part 2.

Inventor: NAKANISHI HIROSHI
IPC: B09B3/00
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To remove chlorides from dust of a sintering apparatus and improve the working ratio of the facility. SOLUTION: Dust of a sintering apparatus 1 is dropped from a storage hopper 2 to a sieve 3 with 3-10 mm mesh to sort a particle with a prescribed particle size or smaller and a prescribed amount of the particle is taken out by a cutting out hopper 4 and inserted into an elution container 7 by an elution container hopper 6. Binary jet flows of water and air are formed in the elution container 7 and as soon as the dust of the sintering apparatus which has a low wettability is added to the binary jet flows, the dust is wetted with water and a slurry is produced and chlorides are easily eluted. The obtained slurry is sent to a dewatering apparatus 10 and taken out as a cake. Consequently, clogging of the outlet of the elution container hopper is prevented and the facility is used at high working ratio and chlorides are efficiently removed by the binary jet flows.

Title: Write enable signal checking systems
Inventor: KATORI MASAYUKI
IPC: G06F12/16
Filed: 1989-05-18
Abstract: PURPOSE:To prevent the generation of misdetection in the abnormal sending of a write enable signal by resetting the write enable signal when scanning-in is executed in writing operation so that a write enable signal checking circuit does not inspect the sending status of the write enable signal. CONSTITUTION:When the write enable signal is sent from a control means 113, data are stored in a storage means 111. A monitoring means 117 inspects the sending state of the write enable signal, but when a scanning means 115 scans the control means 113, an inhibiting means 119 inhibits the monitoring means 117 from inspecting the sending status of the write enable signal. Consequently, the generation of misdetection detecting abnormality in the sending state of the write enable signal in error after executing the scanning-in operation is prevented.

Filed: 1992-04-20
Abstract: PURPOSE:To prevent any step-out motion in a stepping motor by installing a variation limiting means which limits a variation in an analog signal level to the within of an allowable value in this stepping motor. CONSTITUTION:An analog input signal is fed to an analog-to-digital converter 1, feeding an output value calculating circuit 3 via a variation limiting means 2, and speed and step numbers of a stepping motor 7 are calculated. The calculated result is fed to a stepping motor driver 6 via a speed control circuit 4 and a step number control circuit 5, driving the motor 7 by the output, and a position of a pen 8 is controlled and thereby such a waveform as followed to the analog input signal is recorded on a recording sheet 9. At this time when a variation in the analog signal goes beyond the extent allowable value of the motor 7, the variation is limited so as not to exceed the allowable value by the variation limiting means 2, so that any step-out motion in the motor 7 is thus prevented from occurring.
